Scanner

摘要

A method for 3D imaging using phase shifted structured light, in which projection means project multiple phase shifted mask images of a transmission mask on to an object scene, the mask images being captured by a camera to form a camera image, depth information being derived from the camera image by measurement of the camera image and computation from the measurement for each of the phase shifted fringe patterns and a 3D scanner carrying out the method.

1. A method for 3D imaging using phase shifted structured light, in which projection means project multiple phase shifted mask images of a transmission mask on to an object scene, the mask images being captured by a camera to form a camera image, depth information being derived from the camera image by measurement of the camera image and computation from the measurement for each of the phase shifted mask images, in which a stationary transmission mask is projected on to the object scene from multiple illumination positions and the projection means comprise separate illuminants at the illumination positions and the illuminants are operated sequentially so as to create different mask images.
